one-off at the wrist

I abandon

I have to admit I always thought the depiction in Herge’s Prisoners of the Sun to be rather daft; given that the Inca were an ancient civilization whose main god was the sun. I think they might have known more about eclipses far earlier than Europeans?

Being able to predict the location, duration and spread of eclipses is fascinating. The solar annular eclipse in 2021 seems rather grand in shape; as all the solar eclipses near the poles seem? Apparently though most years have two solar eclipses there can be as many as five. Unfortunately the next time that will happen will be in 2206.
